I can't promise you this is right, but I found the following........
Spud (active)
Equipment: Ball Throw the ball up in the air and call a number. Ask number 1 is called, if he catches the ball he calls another number. (Each player has been given his own number.) If he doesn't catch the ball he calls "FREEZE" and takes three giant steps and tries to hit a person with the ball below the waist. If he hits the person then they get a point against them and get to call a new number. If the player misses the person he is trying to hit then he gets a point against him and has to throw the ball up.
